[QUOTE="Buck, post: 8771574, member: 591582"] Bending the port multiple times can add resistance to the air movement in and out of the port, basically. So, you can sometimes use that kind of port to help in situations where you might suspect woofer or port loading in the environment would be poor, but you still need a decent amount of port area to avoid port noise. Also, squeezing the port to one side of the box in a box without much depth helps give the main subwoofer loading chamber a good shape. This helps leave plenty of room around and behind the subs for cooling and subwoofer cone movement, and somewhat helps make sure the air inside of the chamber pressurizes evenly. I'm not sure how strong each effect I explained is, but that's just how I look at it. I do know that the box I showed you an example of was built, and it did work well (according to the owner). I did exact type of layout due to where this box was going in a trunk, and how I thought it would be loading (pressurizing inside of the box chamber) in the trunk. I think the link to the box that you gave here would work fine, but if I could do a multi-bend port here, I would. [/QUOTE]
